New Van Gogh drawing of old man discovered

A newly discovered Vincent Van Gogh drawing that has been hidden in a private collection for more than a century went on display for the first time at an Amsterdam museum on Thursday.

"Study for 'Worn Out'", which depicts an old man sitting in a chair, was sketched by Van Gogh in November 1882 when he was just starting the career that would later produce masterpieces like "Sunflowers".

The owners, a Dutch family which bought the pencil drawing in around 1910, asked the Van Gogh museum to authenticate it and experts confirmed that it was indeed a "new work" by Van Gogh.

"This one has never been seen before anywhere. It's the first time that this drawing is out in the open," Teio Meedendorp, senior researcher at the Van Gogh Museum, told AFP.

"It comes from a Dutch private collection where it has been for a very long time. And this the first time and occasion that the world is able to see it."

The new drawing will be on temporary display at the museum until January 2 before returning to the owners.

"It's quite rare for a new work to be attributed to Van Gogh," added Emilie Gordenker, the director of the Van Gogh Museum.

"We're proud to be able to share this early drawing and its story with our visitors."

The drawing depicts a bald, elderly labourer from a pensioners' home dressed in a waistcoat, trousers and boots, sitting on a wooden chair with his head in his hands.

The Van Gogh museum already owns a similar drawing called "Worn Out", which the artist made at about the same time and said he preferred.

Both drawings are part of a series of "hundreds and hundreds" of sketches that Van Gogh made when he was living in The Hague and learning the artist's trade.

But while letters from Van Gogh to his beloved brother Theo indicated that there was at least one other sketch from the "Worn Out" sessions, which were on or around November 24, 1882, experts didn't know if it still existed.

Meedendorp said it was a "total surprise" to find out that it did. "

"We didn't expect it to be out there but it was out there, so this was a lucky find," he told a press conference.

Van Gogh's vivid post-Impressionist expressionist works like "Irises" and "Starry Night" have become world famous but there has been increasing interest in his earlier, more muted Dutch period.
